Abstract
Events have become central elements in the representation of information from various semantic web applications. It is necessary to develop a formal language for describing and reasoning event knowledge. Description logic is a well-defined knowledge representation language, but it is difficult to represent the event and elements with different characteristics. This paper proposes an event element projection method which is combined with SROIQ to build a new formalization method for event-centered knowledge. Event element projection unifies representation framework of event and event status, establishes the semantic relations between event and its elements. Through element projection and SROIQ, event classes, event instances and event elements can be effectively described in a unified style. An example of formalization on water pollution emergencies ontology is provided based on SROIQ and element projection method. The semantics of event relations based on element projection and reasoning on event relations are also discussed at last.
